What this means for your roof
Atlas explains that buckling can originate in wrinkled underlayment or movement of the wood deck. Its guidance addresses moisture escape, ventilation, approved decking and correction of affected roofing. Persistent buckling may require replacement of damaged shingles after the underlying condition is addressed.
A useful question for your contractor
Will the repair address the deck and underlayment, not just the visible hump?
Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
